CONDENSER Filed Jan. 10., 1930" gwwnto o Kreigh B. Agens Patented July 7, 1931 UNITED STATES PATENT OFFICE KBEIGHiB. AYERS, OF AKRON, OHIO, ASSIGNOR TO THE GOODYEAR TIRE & RUBBER COMPANY, OF AKRON, OHIO, A- CORPORATION OF OHIO CONDENSER Application filed January 10, 1930. serial Nof4l9,878.

This invention relates to condensers and it has, for its primary object, to provide a condenser that will be particularly efficient because of exceptional ability to reduce to a minimum the loss of volatilized liquids.

Prior to this invention, the apparatus employed for condensing volatile liquids were of such construction that a large portion of the liquids evaporated during the process of treatment. This was due primarly to the inefficient manner in which the cooling agent was directed to the condensing surface. Ordinarily, a stream of water was fed through the condenser without any provision for maintaining a continuous supply of cold Water upon the condensing surface other than supplying the water to the condenser. It is obvious that such condenser required a large volume of water to operate even in an ineflicient manner.

This invention is directed to an apparatus embodying a condensing surface of frustoconical shapeoperatively associated with an inlet and an outlet that will permit of continuous circulation of a cooling agent, such cooling agent being circulated directly against the condensing surface by a means positioned within the condenser.

For a better understanding of this invention, reference may now be had to the accompanying drawings, forming apart of this specification, in which: I

Fig. 1 is a cross-sectional view of the apparatus embodying the invention; and

F 2 is a fragmentary cross-sectional view of a construction embodying another form of the invention.

In practicing the invention a receptacle adapted to be heated is provided with a volatile liquid 11 therein and a condenser 12 which serves as a cover for the receptaclelO. The condenser 12 is provided with a condensing surface 13 forming a' chamber of frustoconical shape and an inlet tube 14: for supplying water is centrally positioned within the condenser. A lower end 15 of the tube is disposed adjacent the lower extremity of the condensing surface 13. A baffle plate 16 having its outer edge 17 disposed adjacent the condensing surface 13 is secured to the in-' let t'ubelt. An outlet tube 18, preferably of less diameter than/the inlet tube, is secured to the top of the condenser 12 and is provided to convey the water from the condenser, either by siphoning or by pressure from the inlet tube. 14'.

In the application of the invention illus trated in Fig; 2, aradiator 19 adapted to con tain a volatile liquid 20 is provided with a condenser'22 which is employed as a cap for the radiator. The condenser 21 is provided with a condensing surface 23 of frusto-conical shape and an air inlet tube 24 is centrally positioned within the condenser. One end 25 of the tube terminates adjacent the condensing surface 23 and the other end terminates in a funnel-shaped opening 26 adjacent the top of the condenser. A baffle plate 28 having its outeredge 29 adjacent the condensing surface 23 is secured tothe inlet tube 24. An outlet '30, preferably of less diameter than the inlet, is provided to permit discharge of the cooling agent.

In operating the device, the volatile liquid is placed in the receptacle and heated in any desirable manner. The cooling agent entering through thetu'be strikes the condensing surface adjacent thereto and the baflie platecauses the currents of the cooling agent to be agitated outwardly against the condensing surface (as indicated; by the arrows). Thus a relatively low temperature over the entire condensingsurfa'ce is insuredfby this proper distribution of the agent. The vapor createdwhen a sufiicient degree of heat is obtained rises and'coines into contact with the lower frusto-conical surface of the. condenser or cover. Upon striking this, cool surface, the vapor is condensed and returned to the bottom ofthereceptacle. From the foregoing description it willibe apparent that the invention not ohlynprovides a relatively inexpensive apparatus, but also provides an apparatus that practically obviates the loss of volatile liquids from evaporation, whereas in the apparatus employed heretofore, a greater part of the volatile liquids evaporated when heated.

Although I have illustrated the preferred forms which the invention may assume and have described those forms in detail, it will be apparent to those skilled in the art that the invention is not so limited but that various modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims.

\Vhat I claim is:

1. In combination, a receptacle having a cover adapted to condense vapors issuing from the contents of the receptacle, said cover including a hollow portion extending into the receptacle, and a plate positioned within the hollow portion for facilitating distribution of the cooling agent therein. 7

2. In combination, a receptacle havinga hollow cover adapted to condense vapors issuing from the contents of the receptacle, an inlet and an outlet for permitting circulation of a cooling agent Within the cover, and a baffle plate positioned within the cover for directing currents of the cooling agent adjacent the inner surface of the hollow cover.

3. A condenser for volatile liquids comprising a condensing surface of frusto-conical shape, an air passage having an inlet of funnel-shape and a plate for insuring distribution of the air against the condensing surface.

4. In combination a receptacle having a cover adapted to condense vapors issuing from the contents of the receptacle, said cover having a hollow depending frusto-conical port-ion, an air passage into the cover having an inlet of funnel-shape and a plate positioned within the cover for insuring distribution of the air against the condensing surface.

In combination, a receptacle for volatile liquids, a cover for said receptacle comprising a chamber, an inlet opening for cooling fluid adjacent the bottom of the chamber, an outlet opening adjacent the top thereof, and a baffle plate disposed between the two openings. I

6. In combination, a receptacle for volatile fluids, a cover for said receptacle comprising a chamber having a frusto-conical portion extending into the receptacle, a supply tube for cooling fluid extending downwardly into the chamber into proximity to'the bottom of the chamber, a discharge opening disposed above the discharge opening of the tube, and a baflie plate disposed transversely of the chamber between the two openings.

In witness whereof, I have hereunto signed my name.

Signed at Akron, in the. county of Summit and State of Ohio, U. S. A., this 9th day of January, 1930.
